DOOR OPERATING AND Application led April 30,

This invention relates to door operating and locking mechanisms and is particularly designed for use in connection with the cell doors of a prison.

s The object of the invention is to provide a positive mechanically operated mechanism by means of which each and every door in the system may be locked in either open or closed position andlwhen unlocked lo may be opened or closed by the positive mechanism operated by the keeper from any distant point, such as outside the corridor from a control boX to which he has the key to render the mechanism accessible 15 for operating the doors. The doors may be conveniently arranged and connected in groups and any and all doors of one group, or of all groups, operated from the control box, or any number of selected doors may 2U be operated simultaneously. rIhe doors may be opened and locked in their respective open positions without interferingv with the operation of the other doors.

`To carry out the above and other objects 7 of the invention, which will appear from the description of the mechanism as shown in connection herewith, positive mechanical devices are employed, which `are Vsimple in their construction and not easily tampered with or prevented from performing their required functions and which are easily operated by the person authorized7 all of which will appear more fully in connection with the description of the operative embodiment of the invention illustrated in the accompanying drawings, showing the same as designed and applied to a group of sliding doors.

In the drawings, like parts in the several 4G views have been given the same reference numeral.

The cell doors, one of which is indicated 70 at 1, are hung from T-bars 2, it being understood that ,for the purpose of illustration only one door is shown and the mechanism is describedA in connection therewith, the same being duplicated for other doorsy of 75 the series. 'A bar 3 is attached to the T- bar 2 and extends on either side of the door structure. This bar 3 carries the rollers 4 which ride upon the track 5 when the door is opened and closed by the actuating mechso anism hereinafter described. A h'ousing 6 encloses the mechanism and a guide rail 7 is engaged on its under side by rollers 8 carried by the door structure to hold the door rollers 4 on the track 5. Theserollers 85 are preferably flanged to prevent the same from leaving their respective tracks while permitting a free movement of the door.

The actuating mechanism comprises an actuating bar 9 mounted for longitudinal 90 movement (Fig. 1), riding on rolls 10 which roll on the upper face of the rail 7, the movement being restricted by the lugs 11 on thev upper face of said rail 7 The bar 9 is also held in position on the rolls 10 by the guide 95 rolls 12 carri-ed by the supports 13 from rail 7 This actuating bar 9 carries a number of locking pins 14, one for each door, which are mounted for free vertical. movement in me seceleguides l on the actuating bar 9 and are p0- sitioned to engage in slots, such as indicated at 16, in the bar 3 of the door structure and when so engaged connect the door With the actuating bar 9 and by means ot' which the several doors are, selectively, opened and closed by the movement of, the bar 9.

The actuation of the operating mechanism Will be seen from Figs. 4 and 5. The en closing casing 64 for the control mechanism is attached to the casing 6,-'as shown in Fig. 5, and a removable door, 6 5, is provided with suitable locking means, which prei/'ents access to the control and operating mechanism except when the door 65 is opened by the keeper or other person provided with the key thereto.' Vhen the door G5 is opened, thailand-le 45 is grasped by the operator and pnlgled downwardly, moving the levers 43 and 44 about their respective pivots, 46 and 46, raising thje link 47 connected to the lower end of the lever 43 at 48 and at its upper 4.9. to. a bell-Crank lever 50, which is swungl about its pivot 5 1. The opposite end oli the'lever 5 0; is connected at 52 to a link 5 3 which, in turn, is. connected at 54 tothe lever 55, Which is pivotvally mounted at its lower? end 5 6 andconnected at its uppeil 57 to a connecting bar 5,8. A guide rail SO is engaged byf a guide roll 59 carried' by the lever 55, the lOl'll 59 being flanged maintains the severalrnembers in position and alinement during their movement, as will be. understood.

At theV inner end of the. connectingy bar 53 a gear G1 is mounted, which. gear ridesV upon. a lined gear rack. 62, and operates a movable gear rack attached to or formed in the endof the actuating bar 9, indicated at 63. The

leffect of this connection is to impart twice the amount of` linear movement to the actu-v ating bar 9 as is imparted tothe bar 58 by means of the mechanism just described, as will be. seen.

A rolA-,lierfl' is mounted;` in the lower encv of the locking pins 14, permitting the lock-v ingpins Whichl are disengaged from the door structure, i. e., in raised position, to rice freely on the rail 3a., mountedI on top of the bar 3f attached to theA door struct-ure, as the actuating bar 9, carrying theseY pins i4 is operated` for the opening and closing of other doors.

A door lock control shaft 18, preferably hol-low, is mounted iny and extends through the housing. (if above all oftie. cell; doorsof the cell block. This shaft extends into the operating mechanism housing. 64. (Figs. 4:-5')l and at this end. of the sliaift 18. ay crank. 1-91is attached', which: is. connected' by.Y a link to a crank2l on the han?L- Wheel: shaft 22, operatedby the hand Wheell .413. An indicator disk 24 is also cai-riad by-this latter shaft 22, the hand Wheel 23 and disk- 24 being' positioned o'n'opposte aides. O aininner partition 25 in the housing 64, which partition is provided with a sight opening through which the markings on the disk are visible to determine the position of the mechanism, as shown in Figs. 4 and 5. By means of the hand Wheel 23, the disk 24, shaft 22 and crank 2l may be rotated approximatelydeg. into. three positions, indicated on the disk by the notations LockedfV Center and Open all,7 which are selectively brought into register with the sight opening, rotating the lock control shaft 18 correspondingly, as Will be explained hereinafter. p

The locking and operating mechanism T0 provided for each door is shown in Figs. l to 3v for one door and will; be so described but it Will be understood that the same applies to any desired number of doors, which may be selectively operated in the #J same manner. A clutch member 26 is attached to the control shaft 18 and a co-operating clutch member 27 is positionedadj-acent thereto on the shaft 15S but is independently rotatable thereon. A lug 28 projects from the tace of' clutch member 26l and is positioned and arranged toengage a lug 29 projecting from the adjacent face of .the clutch member when the clutch meinber 26, rotated, by the shaftY 1.81,' is moved to' either ot its extreme positions, approximately deg. apart. One. of these posi-V tions 'is shown. in Fig. 3, corresponding tol the locked position indicated on the disk 24 in Fig. Lugs 30 and 31: proiect from 109 the peripheryof the clutch member 27 andl also another lug 32 to which a flexible cable is attached. for rotating'. the clutch-I niemberf27, as Will be explained hereinafter. An auxiliary shaft 34 is; provided for each door iechanism, mounted in the housing 6, shown in Fig. l. OnA this shaft 34 a locking dog is attached, positioned. below and adjacent the clutch members 2 6 and 27. This locking. dog 35 is provided with a projecting. earl 36 extending (in one position, Fig. 2) between the lugs 30 and 3l. of theA clutch member 27. A lsecond' ear 37 also projects` from the locking dog. 35, being spaced from the ear3 to permit the A--1J lng. 3l. to be. moved therebetween., as indicated in the twoy positions shown inl Figs. 2 and 3.

lVith the partsin the posi-tion shown in Fig. 3, the door is locked, either open or closed, the lower end or foot of the locking dogy 3,5 beingengaged in the slot 1 of tl door structure previously described, the locking dogbeing heldin this position by the ear 36 engaging lug 3l oi clutch member 27.

It now the clutch member 27 is rotated, clockwise, either by rotating the shaft 1S by means of the hand wheel 2V (Fig. 4) to the einen all position, previously described,

causing the lug 28 on clutch member 26 to engage lug 29 on clutch member 27, (unlocking all doors), or by the upward movement of the flexible cable 33 attached to lug 32 of clutch member 27, the lug 31 of clutch member 27 will first engage ear 37 of the locking dog 35 and on further rotation of the clutch member 27 lug engages ear 36, moving the locking dog 35, which also tends to drop by gravity, out of the slot 16 and engagement with the door structure, permitting the locking pin 14 to drop into the slot 16 and thus connect the door (or doors) with the actuating bar 9, as shown in Figs. 1 and 2, (the hand wheel 23 having been .returned to the center position), permitting the same to be opened or closed by means ot the handle 45 and associated mechanism previously described.

' rFhe selector mechanism by means of which any one or more doors may be unlocked and operatively connected. to the door opening and closingmechanism includes a number of flexible cables, previously mentioned and indicated at 33 in Fig. 2, for operating the clutch members and locking dog for each door. A separate cable is provided for each of said mechanisms and are carried through suitable conduits from the doors to the control housing shown in Figs. 4 and 5.

The inner partition in the housing V64 is extended below the operating hand wheel 23 'and is oiiiset in steps, as shown in Figs. 4 and 5, indicated by the numeral 25. The several cables 33 at this end are each connected to a terminal 66, shown in detail in Fig. 8, which terminal is provided with a handle or knob 67 and is mounted for vertical movement in the offset portions of tae partition 25. An indicator 68 is snugly and slidably mounted in the terminal 66.

The indicator 68 is provided with a handle or button 69 at its lower end and also with a pin 7 0 extending through a slot 71 in the side of the terminal 66. A stop pin 72, carried by the partition 25, limits the movement downwardly of the terminal 66 -1 and also controls the movement of the indicator 68 upwardly. A number of indicator control bars, 73, 73a, 7 3b, 7 3c, extend trans-- versely of the terminal and indicator and are provided with slots, 74, etc., (Figs. 7 and 8), which permit the pins 70 to pass therethrough when in the position shown in these figures. Cross bars 75, 75a, .755, 750, 75d, connect the control bars k73, forming therewith a movable frame which is moved in one direction by the springs 76, 76a, (Fig. 6)

its upper position, shown in Fig. 5. When in this position, the frame is moved into the position shown in Figs. 6, 7 and 8, placing the springs 76 under tension, and when the lever 43 is moved downwardly, to open the doors, this cam arm is disengaged from the cam arm 77 and the springs 76 move the frame to the right, in Fig. 6, and the indicator control bars 73 upwardly in Fig. 7 or to the left in Fig. 8, in which position the pin 70, if the indicator 68 has been moved to its lower position shown in dotted lines in Fig. 8, engages beneath the bar 73 and holds the same in its lower position, in which position the marking Open on the same is in sight below the terminal 66. The purpose of this is to indicate that this particular door has been left open.

The operation of this selective mechanism may be briey explained in connection with one door, it being understood that the same applies to any number of doors or combination of different doors which it is desired to operate.

Assume that door to cell No. 16 is to be opened. The cable terminal 66, together with its indicator 68, is pulled down, (see Fig. 4). This causes the cable 33 connected to the clutch member 27 for that particular door to be moved upwardly at the end attached to said clutch member and moves the clutch mechanism and the locking dog from the position shown in Fig. 3 to that shown in Fig. 2 and unlocking the door while engaging the same with the actuating mechanism, as has been previously described. The swinging of the handle downwardly, operating the actuating bar 9, opens this door and also any other doors similarly connected thereto by the pulling down of the terminal connected to the cable operating the clutch and locking dog for such doors, as will be understood. Moving the handle upwardly closes such doors and the hand wheel 23 is now moved from its center position to locked position, rotating shaft 18 and clutch member 26 from the position shown in Fig. 2 to that shown in Fig. 3, causing the lug 28 to engage lug 29, rotating clutch member 27 and causing lug 31 to engage ear 36 on the locking dog 35, moving the same into engagement with the slot 16 of the door structure and raising the locking pin 14 out of engagement therewith. This operation also pulls the cable 33 and Vmoves the terminal, together with its indicator, 66-68, back to its upper position, the pin 70passing through the slot 74 in the control bar 73, which has been moved by the engagement of the cam members 7 7-78, previously described.

Should it be desired to lock the door in itsl open position, the hand wheel 23 and associated parts are operated as described for locking in the closed position, but as the lever 43 is then in its lower position the cam members 'T7-78 are not-engaged and the springs 76 have moved the control bar 73 so that the pin on the indicator 68 is engaged beneath the same and the indicator' is held in its lower position, indicating that this door is open.

To unlock the door previously locked in its open position just described, the hand wheel and associated mechanism is moved to the open all position, operating the clutch members in the manner previously described'. In this case, the locking dog indicated at 35 mounted on the same auxiliary shaft 34 (Fig. l) is operated as described to lock and unlock the door in thisV ating bar 9 moved to operate some other door the lockingV pin 14 will not drop and engage the end of the bar 3. This also permits the door--or any or all doors-to be unlocked in their open position, as when the prisoners are out for meals, etc., and upon returning can close their particular door without requiring the keeper to operate the mechanism separately as each one returns. Upon closing his door, the locking pin falls into the slot, if the actuating bar has been set in the closed position7 and the door prevented from being opened, or if the actuating bar is set in the open position any and all doors may be either opened or closed independently of the locking mechanism or operating mechanism. This is sometimes desirable, as when the cells are being cleaned or inspected, etc., and provides a mechanism which is adapted to all conditions and requirements.
